DOOR-CATCH.

SPECIFICATION forming part of Letters Patent No. 724,229, dated November8, 1904. Application filed December 26, 1902. Serial No. 136,711. (Nomodel.)

To all whom it 'may concern:

Be it known that I, CHARLES A. BoREIN, a citizen of the United States,residing at 47 2 Seventh street, in the city of Oakland, county ofAlameda, and State of California, have invented certain new and usefulImprovements in Door-Catches; and I do hereby declare the following tobe a full, clear, and exact description of the said invention, such aswill enable others skilled in the art to which it most nearly appertainsto make, use, and practice the same.

This invention relates to improvements in door-fasteners, andparticularly to that class wherein a hook swung in a screw-eye in thedoor extends across and engages a similar screw-eye in the door-jamb.This construction is subject to the great disadvantage that the playnecessary to the door and free action of the hook results indisengagement of the hook if the door is rattled or jarred. Thisdisadvantage is particularly annoying on shipboard, where the rattlingand straining are constant. To overcome this disadvantage, which is theobject of this invention, the construction consists of the additions tothe construction described of a spiral spring encircling the shank ofthe hook and tied to the screw-eye by a bridle member and coacting withthe hook in such a manner as to normally take up all play between thehook and said supporting screw-eye.

In the drawings, Figure l is a side elevation of a door-catchconstructed in accordance with this invention, showing the hookdisengaged. Fig. 2 is a similar View showing the hook engaged. Fig. 3 isa plan view from above of the same.

In detail the construction consists of a hook member having its end bentinto an eyelet A, linked into the supporting screw-eye B and having' theextended shank A', terminating in the hook having a slight overhang A3and a pointed extension A. The hook thus formed is adapted to engage ascrew-eye C, screwed allow for warping in into the door-jamb. The spiralspring D encircles the shank A adjacent the eyelet A, between which andthe plate E it expands. The plate E' forms 'a part of the bridle, whichconsists of a strip of sheet metal having the plate E bent at rightangles thereto, through which 50 i the shank A extends, and the backwardextension E, having the circular head E2, through which the stem of thescrew-eye extends.

The invention is assembled, applied, and operated as follows: The hookmember having been formed and linked to its supporting screw-eye, thespiral spring is slipped onto the shank before or after the hook isformed, the plate of the bridle is passed over the shank, following thespring, and the stem of the sup- 6o porting screw-eye passed through thecircular head of the bridle and screwed into the door the properdistance from the screw-eye in the door-jamb. The influence of thespring controlled by the bridle tends to normally take up the play ofthe hook member, so that the operative position Fig. 2 is assumedagainst the tension of the spring, which causes the hook to hug thescrew-eye C, the overhang A3 preventing disengagement of the hook exceptby design. rIhe bridle may be attached to the screw-eye B to liealongside of the eyelet A, instead of, as shown, to permit the lateralswing of the hook member. The bridle may spring bent back upon itself toperform the same function.

The tension of the spring accomplishes the further purpose of preventingrattling of the door or window to which it is applied by hold- 8O ingthe parts snugly in place.
